Another solution is to use CGI effects…"‘Rogue One’ is the road map," says one “Star Wars” source, referring to Lucasfilm resurrecting Peter Cushing and making Fisher young again in the current hit.
It sounds like their plan is to double down on the video game cutscenes. Maybe PIXAR can take over at some point.
I always take anything from a “source” with a grain of salt.
I think they could beautifully write in Leia’s death to serve as a tribute to Carrie Fisher and an emotional sendoff for the fans for both the character of Leia and Carrie Fisher.
